CONCORD, N.H. – A traveling medical technician accused of causing a hepatitis C outbreak in New Hampshire wrote a suicide note saying he "couldn't handle this stress anymore" the week before his arrest, according to a police report.

David Kwiatkwoski was arrested July 19 at a Massachusetts hospital six days after police found him apparently impaired in a hotel room scattered with prescription pills, according to police in Marlborough, Mass. Kwiatkowski is being held on federal drug charges in New Hampshire, and authorities are trying to determine if he spread the virus in seven other states.

Although federal authorities previously indicated that Kwiatkowski might have tried to harm himself in the days before his arrest July 19, the Marlborough police report includes new details, including a list of six prescription drugs that were found in Kwiatkowski's hotel room. Officers also smelled a strong odor of alcohol on Kwiatkowski's breath, and he slurred his words when he spoke, police said.
